  • the second application is carried out by operating the actuating means 19 again in the same way and with the same effect as in the first subsequent partial operation. Again, a pressure point means 27 is destroyed again.
  • the discharge of the medium from the first chamber 13 a is achieved by further displacement of the two plugs 14 of the container 12 in the direction of the discharge opening 18.
  • the media volume that is discharged is determined by the actuation path of the subsequent partial actuation, here in the first partial actuation as well as in the second partial actuation of the partial actuation path b .
  • the container, an ampoule, capsule or carpule is now emptied. Relevant parts of the discharge device are destroyed after use and can not be reused. It is therefore a disposable system and can then be recycled. It is advantageous that the discharge is mainly made of plastic, which can be selected according to type.
  • the crimp closure and the needle are formed as metallic parts, wherein optionally also the crimp closure is made of plastic.
  • the plugs 14 are often made of an elastomer or rubber. They too can be recycled. So is particularly advantageous in such a design of the discharge the low use of different materials and the small number of metallic components. No metallic springs, pins or other metallic elements other than those mentioned above are required.
  • the subsequent partial operations which serve the discharge of medium, can be carried out directly one after the other and without any additional hand movements.
  • the handle of the discharge so it is easy to perform despite the required mixture of the medium from the media components.
  • An essential advantage of the invention is to be seen in this simple handling.
